What is a VPN and How does it work? Your Guide to Best Security Practice 

VPN stands for “Virtual Private Network” and describes the opportunity to establish a protected network connection when using public networks. VPNs encrypt your internet traffic and disguise your online identity.

This makes it more difficult for third parties to track your activities online and steal data. The encryption takes place in real time.

What is a VPN and How does it work

There are about 1.5 billion VPN users worldwide, and the numbers are still growing. This is the right time to know what a VPN is and how it works.

Virtual Private Network(VPN) is a service that secures your connection while you browse the internet. It employs technology to protect your data from cyber attackers, malware, and agencies.

How does a VPN work?

A VPN routes your device’s internet connection through a secure tunnel rather than your daily or regular internet service provider (ISP) servers. In the process, it encrypts your information, such as IP address, location, and other sensitive data, so that it reaches your desired location. 

What are the benefits of a VPN connection?

By using a VPN your online data transmission is protected from outside access and hidden. Unencrypted data can be viewed by anyone with network access who wants to see it. By using VPN, hackers, and cyber criminals cannot access your data.

Here are some benefits:

Secure encryption: An authentication code is needed to unlock the data or information. Without one, millions of machines cannot crack the code. Your browsing is concealed by using a VPN, even on public networks.

Disguising your Location: VPN servers act as your proxies on the internet. It is impossible to pinpoint your exact location by using a VPN because the demographic location data comes from a server in another state.

Access to regional content: This access is not always available everywhere. If you want to access regional content, a VPN can make it easy to access it.

Secure data transfer: You might need to obtain crucial data that is situated on your company’s network when you work remotely. For this kind of information, it needs a secure connection for privacy reasons.

The History of VPNs

VPN history initially came back in 1996, when a Microsoft employee (many sources say Gurdeep Singh Pall) started inventing the Peer to Peer Tunneling Protocol (PPTP). Then in 1999, the specification was published.

The predecessors of the VPN and Early VPNs 

Internet security has existed since the US Department of Defence began looking at techniques to secure Internet communication data in the 1960s. As a result, ARPANET was developed, which helped TCP/IP get off the ground.

The risk of exposure became apparent as more networks and gadgets were connected, though. The first iteration of a contemporary VPN, known as swIPe, was developed in 1993 by a team from Columbia University and AT&T Bell Labs. 

Wei Xu created IPSec the following year, while Gurdeep Singh-Pall from Microsoft created PPTP in 1996. In the early 2000s, enterprises were the primary users of the initial VPNs. 

However, as security breaches escalated in the early 2010s, there was a sharp spike in demand for consumer-friendly VPNs.

Why should you use a VPN connection?

There are many advantages to using VPN. 77% of people use VPNs for personal use and 50% for business use.

We should use VPNs for security purposes, to protect personal information, and to mask internet activity.

You never know who might be watching your online activity or who is stealing from you, such as passwords, sensitive information, financial data, or even your complete identity. VPN would help you to preserve all of these issues.

What should a good VPN do?

The following are the features that a good VPN should have:

Secure Access: The primary job of a VPN is to hide your IP address from your ISP and other third parties. Without any risk, a good VPN will always allow you to transmit data online but you and the VPN provider see it.

Encryption of Protocols: With the use of a VPN, you should be shielded from leaving cookies, internet history, and other types of traces. Because it prevents unauthorised parties from accessing private data, including financial and personal information, and other website content, cookie encryption is particularly crucial.

Kill switch: VPN kill switch automatically disconnects your device from the internet if you have a VPN connection. Whenever your VPN turns off, a kill switch blocks unsecured internet connection until your VPN connection is restored, ensuring that your data and privacy are protected. 

Two-factor authentication: A strong VPN verifies each user who attempts to log in by employing several authentication techniques. For instance, you could be asked for a password before a code is delivered to your mobile device.
